Thanks for this calibre docker. Love the Modern UI. I'm using Marvin 3 on iOS and I'm getting an error when i try to download a book. I configured marvin with opds and tried with and without credentials.
I can browse the library and view the metadata. The issue downloading the epub.
Error: The username and password you entered for this catalog are incorrect or Marvin dos not the support the catalog's authentication method.
